309 stainless steel round bar
309 is an austenitic chromium-nickel stainless steel known for its
high corrosion resistance and strength. 309 has the same machining
properties as 304, and can be roll formed, stamped, and drawn
easily.
Due to its properties, especially its ability to work under
high-temperatures, you will find 309 in a wide variety of
applications including:
Boiler baffles, furnace components, oven lining, fireboxes, kiln
Liners, sulfite liquor handling equipment, carbuizing-annealing
boxes, heat exchangers, aircraft engines, automotive exhaust parts
